Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77124, here are decompositions:
- 23 + 77101 = 77124
- 31 + 77093 = 77124
- 43 + 77081 = 77124
- 83 + 77041 = 77124
- 101 + 77023 = 77124
- 107 + 77017 = 77124
- 163 + 76961 = 77124
- 181 + 76943 = 77124
Showing the first eight; more decompositions exist.
